Question

The following is considered as one of the fibre properties, prior selection to Spinning of Cotton

• A. Bending Rigidity
• B. Fused Index
• C. Maturity
• D. Surface Friction

Hint:

The important fibre properties evaluated before cotton spinning include: \[ \begin{aligned} &\bullet\ \text{Length} &\bullet\ \text{Strength} &\bullet\ \text{Fineness} &\bullet\ \text{Uniformity} &\bullet\ \text{Micronaire} &\bullet\ \textbf{Maturity} \end{aligned} \] Remember: \[ \boxed{\text{More Mature Fibre } \Rightarrow \text{Better Spinning } \Rightarrow \text{Better Yarn Quality}} \] Maturity is one of the most frequently asked fibre properties in textile engineering examinations.

Answer 1

The Correct Option is C

Concept:

Before cotton fibres are selected for spinning, they are evaluated based on several important fibre properties that determine spinning performance, yarn quality, and fabric characteristics.

Some of the important fibre properties are:

• Fibre Length
• Fibre Fineness
• Fibre Strength (Tenacity)
• Uniformity Ratio
• Fibre Maturity
• Fibre Elongation
• Micronaire Value
• Colour and Trash Content

Among these, maturity is an important property because it indicates the degree of development of the cotton fibre. Mature fibres have thicker cell walls, higher strength, better dye absorption, and produce superior-quality yarn.

Step 1: Understand fibre maturity.

Fibre maturity refers to the extent of development of the cotton fibre during its growth.

A mature fibre has:

• Thicker cell wall
• Higher strength
• Better dye uptake
• Improved spinning performance

Immature fibres generally result in:

• More neps
• Weak yarn
• Uneven dyeing
• Poor fabric appearance

---

Step 2: Examine the given options.

• (A) Bending Rigidity: Relates to fibre stiffness and is not a primary selection criterion for cotton spinning.
• (B) Fused Index: Not a standard property used in cotton fibre evaluation.
• (C) Maturity: A key fibre property that directly affects spinning efficiency and yarn quality.
• (D) Surface Friction: Influences fibre processing but is not one of the principal selection parameters.

Final Answer:

The important fibre property considered before cotton spinning is

\[ \boxed{\text{Maturity}} \]

Therefore, the correct answer is

\[ \boxed{\text{Option (C)}} \]
